General procedure for using anti-ice in flight?

• A. Increase engine power to max to blow off ice.
• B. Turn off anti-ice systems to reduce drag.
• C. Maintain current settings and wait for conditions to improve.
• D. Use the appropriate anti-ice/ICE protection modes per the flight crew procedures when icing conditions are encountered.

Answer: (D)

In-flight icing must be managed with the aircraft’s designed anti-ice system, activated according to the flight crew procedures. When icing conditions are encountered, you select and use the appropriate anti-ice/ICE protection modes for the surfaces that need protection (such as wings and engines) and set them to the mode required for the situation. The goal is to actively heat or protect those surfaces to prevent ice buildup, maintain lift and controllability, and avoid ice shedding or engine ice-related issues. Simply increasing power to blow ice off isn’t a reliable or proper method, turning anti-ice off would allow ice to accumulate and degrade performance, and waiting for conditions to improve ignores the persistent nature of icing. Following the prescribed anti-ice modes ensures safe, effective protection throughout the icing encounter.
